In this video We explain how to check variable frequency drive with Multimeter
for testing first we explain vfd input and output circuit
vfd input circuit have rectification circuit which convert ac supply into dc supply and output circuit is inverter circuit
in inverter circuit we have 6 Igbt
inverter circuit convert dc supply into variable ac supply
in this video for checking vfd we apply diode checking concept
for more information learning about vfd testing just watch and learn
